Mini-type automatic aerosol fire suppression apparatus

Abstract

The present invention relates to a mini-type automatic aerosol fire suppression apparatus, comprising top cap (1), thermal insulating layer (3), inner cylinder (4), outer cylinder (5), bottom cap (7), sensing element (8), screen (9) and igniter (11), wherein a chemical agent (6) and a cooling layer (10) are installed in the inner cylinder (4), the thermal insulating layer (3) is installed between the inner cylinder (4) and the outer cylinder (5), and the sensing element (8) is designed to sense fire. The volume of the apparatus is not greater than 0.05 m3. Compared to that in the prior art, the apparatus is delicate and easy to install, and is suitable for quick local fire suppression, and can get twice the result with half the effort in such applications.

Description

FIELD OF THE INVENTION[0001]The present invention belongs to the technical field of gas fire suppression apparatuses, and relates to a mini-type automatic aerosol fire suppression apparatus that is applicable to a variety of fire hazard locations where the space is small and enclosed and the equipment is of high value and unattended.BACKGROUND OF THE INVENTION[0002]Nowadays, aerosol fire suppression apparatuses are widely applied due to their advantages such as excellent fire suppression performance, safety, reliability, stability, environment friendliness and easy operation.

AI Technical Summary

Benefits of technology

[0004]In view of the present situation in the prior art, the object of the present invention is to provide a mini-type automatic aerosol fire suppression apparatus that is applicable to a variety of fire hazard locations where the space is small and enclosed and the equipment is of high value and unattended.

[0015]The advantages of the aerosol fire suppression apparatus include: both the temperature of the wall and the temperature at the jet orifice are low, and the apparatus is compact and small, whose volume is not greater than 0.05 m3, and therefore is applicable to a variety of small spaces.

Problems solved by technology

However, existing aerosol products can't meet the market demand.

In many small spaces where power utilization, distribution, and transformation are involved, such as transformers, distribution cabinets, engine compartments and luggage compartments on vehicles, etc., and at locations on aircrafts, vehicles, or ships where gasoline, diesel oil, or aviation kerosene is used for propulsion, fire resulted from fire hazards such as aged cables and wires, fuel leakage, and harsh environment, etc. is usually difficult to discover and detect in the early stage.

Often, a spark may cause a severe fire disaster so that severe personal injuries and death and equipment damage can happen.

In these circumstances, quick local fire suppression may get twice the result with half the effort.

However, no mini-type automatic fire suppression apparatus in which the charge amount is less than 1 Kg and the temperature at the jet orifice is lower than 150° C. is seen in the market yet.
